We are still working on getting morphium 4.0.0 done. We are behind schedule a bit but want to explain here, what is going on at the moment:

  • complete new ObjectMapper implementation based on Jackson. Using this, we are about 30% faster on average (even twice as fast in some cases). And we use a standard lib here
  • new messaging functionalities. This is going to be the new core of Morphium, the Messaging! We put a lot of effort in this component, improved a lot, made it faster
  • de-cluttering of the API and of the code on a lot of places

Unfortunately V4.0.0 is not 100% compatible with the predecessors. It might be necessary to migrate data - although not very probably. If you need assistence with that, please contact us on google-groups or githup.

All of that is taking more time, than estimated. But BETA4 of morphium 4.0.0 can be downloaded on maven central:

 <dependency>
            <groupId>de.caluga</groupId>
            <artifactId>morphium</artifactId>
            <version>4.0.0-BETA4</version>
        </dependency>

In order for Morphium to work, you need to add the mongo drivers libs to your dependencies. We tested morphium with V3.8.0 of the drivers libs, but later versions should also work. (this is one of the reasons, why morphium does not create a direct dependency to the driver! Use the version you have in your project already, if not, use 3.8.0)

  <dependency>
            <groupId>org.mongodb</groupId>
            <artifactId>bson</artifactId>
            <version>3.8.0</version>
        </dependency>
        <dependency>
            <groupId>org.mongodb</groupId>
            <artifactId>mongodb-driver-core</artifactId>
            <version>3.8.0</version>
        </dependency>
        <dependency>
            <groupId>org.mongodb</groupId>
            <artifactId>mongodb-driver</artifactId>
            <version>3.8.0</version>
        </dependency>

Happy hacking!
